For evidence, look no further than Wes Welker's wife and her nasty Facebook rant about Ray Lewis, which has blown up in her face and in the face of the New England Patriots' organization, too.

Not dealing well -- obviously -- with the Ravens' 28-13 win over her husband's Patriots in the AFC Championship game Sunday, Anna Burns Welker wrote this on Facebook about the Ravens' legendary and soon-to-be-retired inside linebacker:

"Proud of my husband and the Pats. By the way, if anyone is bored, please go to Ray Lewis' Wikipedia page. 6 kids, 4 wives, acquitted for murder. Paid a family off. Yay! What a hall of fame player! A true role model!"

Reaction to the vicious, sour-grapes screed was swift and overwhelming, and Anna Welker quickly issued the standard, mealy-mouthed apology Tuesday through a high-powered PR firm.

"I'm deeply sorry for my recent post on Facebook," she wrote. "I let the competitiveness of the game and the comments people were making about a team I dearly love get the best of me. My actions were emotional and irrational and I sincerely apologize to Ray Lewis and anyone affected by my comment after yesterday's game."

The idea of taking to social media when one is "emotional and irrational" should be the object lesson for everyone connected to the NFL.

Don't tweet or post when you're angry or frustrated. In fact, don't tweet or post even when you're merely irritated.

Antonio Cromartie discovered that truth a few years ago when he ripped the food the San Diego Chargers were serving in training camp.

Not only did this violate a Chargers' rule about talking about team matters, he came across as another whiny, pampered star at a time when people were losing their jobs and worrying about where their next meal would come from.

But with social media so deeply ingrained in the lives of young, wealthy NFL players and their families who feel invincible as it is, don't look for them to stop taking to Facebook, Twitter, et. al. when they're upset.

It's a lesson people like Anna Burns Welker only seem to learn the hard way.
